net: ena: Update XDP verdict upon failure
The verdict returned from ena_xdp_execute() is used to determine the fate of the RX buffer's page. In case of XDP Redirect/TX error the verdict should be set to XDP_ABORTED, otherwise the page won't be freed. Fixes: a318c70ad152 ("net: ena: introduce XDP redirect implementation") Signed-off-by: Shay Agroskin <shayagr@amazon.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
